From 1931 to 1950 (and even beyond), Electro-Vox recorded all of the "airchecks" from the NBC/Mutual-Don Lee Radio/TV KHJ-TV radio station at 5515 Melrose Avenue (virtually across the street), including performances by Bing Crosby, Bob Hope, Jack Benny, George Burns and Gracie Allen.

Many Capitol Records artists used Electro-Vox as a rehearsal space and a studio to record their demos, including (but not limited to), the King Cole Trio, Henry Mancini, Jerry Lewis, Herb Alpert, Frank Sinatra, Cole Porter, Harold Arlen, Dinah Shore, Eddie Cantor, Judy Garland, Sammy Fain, Spade Cooley, the Sons of the Pioneers, Plas Johnson, Burt Bacharach, and Johnny Mercer.

Demos recorded at Electro-Vox included "Moon River", "Mona Lisa", "Love Is a Many-Splendored Thing", "Silver Bells", and "Buttons and Bows".

Tex Ritter, a pioneer of American country music, from the mid-1930s into the 1960s, recorded and broadcast many live radio shows at Electro-Vox during the same time period.

Gordon Phillips (known as the "Voice of the LA Times"), was the Director of Promotion and Public Relations, and had a long-standing, quality, working relationship with Electro-Vox.

"Bird", "Grace of My Heart" and "For The Boys" were just a few of many well-publicized motion pictures during the time period of the 1980s and 1990s, that had important scenes to their respective movies filmed at Electro-Vox.
